WATCH! Justin Bieber & Tina Fey Are Total BFFs Now! We Can't Wait To See Them Together On 'SNL' Tonight!

Just look how much fun Justin & Tina are having backstage at Saturday Night Live. It’s going to be a good episode!

Rehearsing for live TV can be stressful and tiring… but leave it to Justin Bieber and Tina Fey to have fun in any situation! The duo — who will be appearing on Saturday Night Live at 11:30 p.m. ET tonight on NBC — took some time out of last night’s rehearsal to film a special message for their fans on Twitter, which was uploaded by the Biebs’ manager Scott “Scooter” Braun. Not only did Justin promise to see Tina’s new movie Date Night, but Tina even offered up a little trick to help the movie make a few extra bucks at the box office. It’s hilarious. Check it out!

A few hours later, Justin took to his own Twitter account after seeing Date Night. “Great movie tina,” was his short-but-sweet review of her comedy, which also stars Steve Carell and Mark Wahlberg, among others.

Aww! Biebs… such a gentleman. BFFs, will you be tuning in to watch him perform tonight?
